Referring to fig. 1-17, the present invention provides a feeding and discharging rack for a pipe cutting machine, comprising: a plurality of feeding mechanisms 100 and discharging mechanisms 200 which are arranged vertically to the length direction of the pipe cutter 93; the feeding mechanism 100 and the discharging mechanism 200 are formed by arranging a plurality of material rack modules at intervals; the material rack module comprises a rack 1, a material storage mechanism 2 and a transverse moving material conveying mechanism 3, wherein the material storage mechanism 2 and the transverse moving material conveying mechanism are arranged on the rack 1; the material storage mechanism 2 on the feeding mechanism 100 is driven by a feeding synchronous driving mechanism 401, and the material storage mechanism 2 on the blanking mechanism 200 is driven by a blanking synchronous driving mechanism 402; a plurality of material storage stations 20 for storing workpieces are arranged on the material storage mechanism 2; the transverse moving material conveying mechanism 3 on the feeding mechanism 100 is used for conveying the workpieces to be processed on the material storage station 20 to the pipe cutting machine 93; the transverse moving material conveying mechanism 3 on the blanking mechanism 200 is used for conveying the machined workpieces on the pipe cutting machine 93 to the material storage station 20 of the material storage mechanism 2. It should be understood that the workpiece may be a circular tube, a rectangular tube, an i-beam, a channel, an angle iron, or other shapes.

The feeding mechanism 100 and the discharging mechanism 200 are arranged according to the actual requirement of the pipe cutting machine and are arranged in corresponding numbers. Specifically, the feeding mechanism 100 is set to five groups, and the discharging mechanism 200 is set to six groups. The longest feeding length is 12m, and the shortest feeding length is 3 m; the shortest blanking time is 0.5m, and the longest blanking time is 12 m. The feeding mechanism 100 and the blanking mechanism 200 adopt the same design (material rack modules), namely the feeding mechanism 100 and the blanking mechanism 200 are different in the movement direction of the material storage mechanisms 2 (namely the movement direction of the feeding synchronous driving mechanism 401 and the blanking synchronous driving mechanism 402), and the arrangement can greatly simplify the structure of the feeding and blanking racks, reduce the production difficulty and improve the production efficiency; in addition, the number of the feeding mechanisms 100 and the blanking mechanisms 200 can be increased or decreased according to the processing length and position of the laser pipe cutting machine, and the universality is further improved.

The material storage mechanism 2 on the material loading mechanism 100 is in transmission connection through a material loading synchronous driving mechanism 401, and the material storage mechanism 2 on the material unloading mechanism 200 is in transmission connection through a material unloading synchronous driving mechanism 402, so that the material storage mechanism 2 on the material loading mechanism 100 and the material storage mechanism 2 on the material unloading mechanism 200 are better in linkage and synchronism; the transverse moving material conveying mechanisms 3 on each material rack module are provided with independent power and are electrically connected with the control center, when feeding is performed, the feeding synchronous driving mechanism 401 drives the material storage mechanisms 2 on the feeding mechanism 100 to move synchronously, so that workpieces to be processed on the material storage stations 20 are conveyed to the material receiving positions of the transverse moving material conveying mechanisms 3, and the control center controls part or all of the transverse moving material conveying mechanisms 3 on the feeding mechanism 100 to move synchronously, so that the workpieces to be processed are conveyed to the laser pipe cutting machine; during blanking, the control center controls part or all of the transverse moving conveying mechanisms 3 on the blanking mechanism 200 to move synchronously, supports the machined workpieces on the laser pipe cutting machine, conveys the workpieces to the storage station 20 of the blanking mechanism 200 (the storage station 20 is the storage station 20 closest to the laser pipe cutting machine), and finally synchronously drives the storage mechanism 2 on the blanking mechanism 200 to move synchronously through the synchronous driving mechanism 402 of the blanking synchronous driving mechanism 402, so that the workpieces are far away from the laser pipe cutting machine, and workers can conveniently unload the workpieces; in the pipe cutting process, the transverse moving material conveying mechanism 3 on the feeding mechanism 100 can also provide follow-up support for the workpiece, assist the laser pipe cutting machine in cutting the workpiece, and improve the processing precision; in addition, in order to enable the transverse moving material conveying mechanisms 3 on the feeding mechanism 100 and the discharging mechanism 200 to move to avoid chuck assemblies (a front chuck and a rear chuck) on the laser pipe cutting machine, when the chuck assemblies of the laser pipe cutting machine gradually approach a certain transverse moving material conveying mechanism 3 to a set distance, the control center controls the transverse moving material conveying mechanism 3 to exit, namely the transverse moving material conveying mechanism 3 moves towards the material storing mechanism 2, and the follow-up support for workpieces is cancelled.

When the material storage station 20 stores workpieces such as rectangular pipes, character steels, channel steels, angle irons and the like according to the requirement of a machining plan, a worker selects the support plate 5 to be installed on the first chain 23, and then horizontally places the workpieces on the support plate 5; the working principle of the feeding mechanism 100 is as follows: the feeding synchronous driving mechanism 401 on the feeding mechanism 100 moves forward to drive the first driving sprockets 21 on the five groups of feeding mechanisms 100 to move forward, each first driving sprocket 21 drives one first driven sprocket 22 and one first chain 23 to move, so that the workpieces on the storage station 20 are sequentially transferred to the material taking position of the transverse moving material conveying mechanism 3, and finally the workpieces are centered and positioned through the transverse moving material conveying mechanism 3 and transferred to the laser pipe cutting machine to be processed. The working principle of the blanking mechanism 200 is as follows: each of the traverse material transporting mechanisms 3 supports a workpiece which has been processed, at this time, the traverse material transporting mechanisms 3 move the workpiece which has been processed toward the direction of the material storing mechanism 2, the blanking synchronous driving mechanisms 402 on the blanking mechanisms 200 move in opposite directions to drive the first driving sprockets 21 on the six groups of blanking mechanisms 200 to move in opposite directions, and each of the first driving sprockets 21 drives a first driven sprocket 22 and a first chain 23 to move in opposite directions, so that the material storing station 20 is transferred to the material receiving position of the material storing mechanism 2, thereby replacing the material storing station 20 on which the workpiece has been processed.

When the material storage station 20 needs to store round pipes according to a processing plan, a worker selects the round pipe support 6 to be installed on the first chain 23, and then places the round pipes on the round pipe support 6 to prevent the round pipes from rolling and shifting.

The material loading section of the first chain 23 is supported by the supporting plate 12 in the transverse movement process, so that the gravity of the workpiece is transmitted to the supporting plate 12, on one hand, the increase of the transmission load of the first chain 23 caused by the concentration of excessive gravity on a waist-shaped transmission part can be avoided, on the other hand, the jolt brought by chain transmission can be reduced by rolling and pressing the connecting shaft on the first chain 23 on the supporting plate 12, and the transmission stability and accuracy are improved.

In practical applications, the feeding mechanism 100 and the discharging mechanism 200 are respectively provided with independent synchronous driving mechanisms, so that the feeding mechanism 100 and the discharging mechanism 200 can be independently controlled synchronously. When the synchronous driving motor 41 on the feeding mechanism 100 moves (taking forward motion as an example), the second driving sprocket 42 drives the second driven sprocket 43 and the second chain 44 to move, under the action of the synchronizing shaft 45, the plurality of first driving sprockets 21 connected with the synchronizing shaft 45 also synchronously rotate towards the direction of the pipe cutting machine, so that each material storage mechanism 2 can synchronously rotate, workpieces to be processed are conveyed to the material storage station 20 close to the pipe cutting machine, and the material conveying mechanism 3 is transversely moved to convey the workpieces on the material storage station 20 to the pipe cutting machine; when the blanking is needed, the workpiece which is processed is transferred to the material storage station 20 which is closest to the pipe cutting machine by the transverse moving material conveying mechanism 3, the moving direction of the synchronous driving motor 41 is opposite to that of the feeding, the workpiece is gradually transferred in the direction away from the pipe cutting machine by taking reverse movement as an example, and similarly, the plurality of blanking material rack modules synchronously move under the action of the synchronizing shaft 45, the workpiece which is processed is synchronously transferred, and through the arrangement, the synchronism and the linkage of the feeding material rack modules and the blanking material rack modules are favorably improved. The chain transmission mode is high in transmission efficiency and good in operation stability, and stable movement of the workpiece on the material storage mechanism 2 is guaranteed.
